Enamelled Copper Clad Aluminum Wire

1.Good conductivity. 2.Save copper resource, reduce the produce cost.

Performance features:

It has good performance of high temperature-resistance, cold-resistance, radiation-resistance, softening-resistance, and freeze-resistance. The heat-resistance temperature is higher than that of Polyesterimide polyamide-imide compound copper over-coated aluminum enameled wire. It has good electrical conductivity. The density of aluminum is low (Just 40 percent of that of copper enameled wire). It is light and the length in each unit weight can reach 2.5-2.7 times than that of copper enameled wire. By using this material, the cost can be reduced by 30 percent above. The heat-resistance temperature can reach as high as 240 centigrade.
